Detailed explanation-1: -A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G) and thymine (T). In RNA, the base uracil (U) takes the place of thymine.
Detailed explanation-2: -DNA is made up of four building blocks called nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C). The nucleotides attach to each other (A with T, and G with C) to form chemical bonds called base pairs, which connect the two DNA strands.
Detailed explanation-3: -Nucleotides contain three characteristic components: a nitrogenous base, a pentose, and one or more phosphate groups. The nitrogenous bases are derivatives of two parent heterocyclic compounds, purine and pyrimidine. The major pyrimidine bases are cytosine, thymine, and uracil.
Detailed explanation-4: -A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine.
Detailed explanation-5: -Nucleotides that make the DNA strands contain deoxyribose sugar, phospate molecule and one nitrogenous base out of adenine, guanine, thymine and cytosine. Uracil is never a part of nucleotide of DNA.
